Related Art

In 5G systems, Enhance Mobile Broadband (eMBB) and Ultra Reliable andLow Latency Communication (URLLC) are two typical service types. A newModulation and Coding Scheme (MCS) table has been defined for URLLCservices in the 3rd Generation Partner Project (3GPP) New Radio (NR)Release 15.

In order to support URLLC services of higher requirements, for example,higher reliability, lower latency (0.5-1 ms), etc., the 3GPP RadioAccess Network (RAN) #80 session had approved a Study Item (SI) of URLLCenhancement of NR Release 16, in which enhancements to scheduling/HybridAutomatic Repeat reQuest (HARQ)/Channel State Information (CSI) timelineare a key point to be studied.

SUMMARY

The inventor finds through researches that applications havinglow-latency requirements need to feed back a HARQ/CSI quickly whileapplications having no low-latency requirements may feedback a HARQ/SCIslowly; therefore, how to configure a HARQ/SCI feedback in view ofdifferent latency requirements is a key problem to be solved.

In view of the above problems, the disclosure provides a solution. Itshould be noted that embodiments of the disclosure and characteristicsof the embodiments may be mutually combined arbitrarily.

The disclosure provides a method in a User Equipment (UE) for wirelesscommunication, wherein the method includes:

receiving a first signaling;

receiving a first radio signal in a first time window; and

transmitting a feedback on the first radio signal in a second timewindow.

Herein, the first signaling is used for determining time-domainresources occupied by the first radio signal; a first time-domaindeviation is a deviation in time domain between the second time windowand the first time window; when the first signaling carries a firstidentifier, the first time-domain deviation is one of K1 first-typecandidate deviation(s), and K1 is a positive integer; when the firstsignaling carries a second identifier, the first time-domain deviationis one of K2 second-type candidate deviation(s), and K2 is a positiveinteger; the first identifier is different from the second identifier,and at least one of the K2 second-type candidate deviation(s) isdifferent from all of the K1 first-type candidate deviation(s).

In one embodiment, the problem to be solved by the disclosure is: how toenhance the scheme of configuration of Hybrid Automatic Repeat reQuestACKnowledgement (HARQ-ACK) feedback latency in view of the lower-latencyrequirements in NR Release 16.

In one embodiment, the problem to be solved by the disclosure is asfollows: in NR Release 15, the configuration of HARQ-ACK feedbacklatency may be indicated through Downlink Control Information (DCI) (aPhysical Downlink Shared CHannel (PDSCH)-to-HARQ_feedback timingindicator field in DCI format 1_0 or 1_1) or configured by RadioResource Control (RRC) (when the PDSCH-to-HARQ-feedback timing indicatorfield is a 0 bit in DCI format 1_1). The method of indication through aDCI is to select one latency value from one HARQ-ACK feedback latencyrange configured by an RRC, while the method of configuration through anRRC is that the RRC configures one HARQ-ACK feedback latency. To supporta HARQ feedback with a lower latency in NR Release 16, how to enhancethe above method of DCI indication or the above method of RRCconfiguration is a key problem to be solved.

In one embodiment, the essence of the above method is that: the firstsignaling is a DCI signaling for scheduling a PDSCH, the first radiosignal is a PDSCH scheduled by the first signaling, the feedback on thefirst radio signal is a HARQ-ACK, the first time window is a slot inwhich the PDSCH is located, the second time window is a slot in whichthe HARQ-ACK is located, the first time-domain deviation is a feedbacklatency of the HARQ-ACK relative to the PDSCH, and the first identifierand the second identifier are two different Radio Network TemporaryIdentifiers (RNTIs) used for CRC scrambling of the DCI. If detected thatthe DCI is scrambled with the first identifier, the feedback latency ofthe HARQ-ACK relative to the PDSCH belongs to the K1 first-typecandidate deviation(s); if detected that the DCI is scrambled with thesecond identifier, the feedback latency of the HARQ-ACK relative to thePDSCH belongs to the K2 first-type candidate deviation(s). The adoptionof the above method has the following benefits: the RNTI used forscrambling the CRC of the DCI is associated to a HARQ-ACK feedbacklatency range, thus the HARQ-ACK feedback latency range may bedetermined implicitly by identifying the RNTI; on one hand, for the caseof selecting one latency value from the HARQ-ACK feedback latency rangethrough the DCI signaling, the above method avoids the case that morebit overheads are introduced into the DCI to support a lower latency; onthe other hand, for the case of indicating the HARQ-ACK feedback latencythrough the RRC signaling, multiple HARQ-ACK feedback latency rangesassociated to the RNTI are configured, which solves the problem thatdifferent services have different requirements on latency.

For the case of selecting one latency value from the HARQ-ACK feedbacklatency range through the DCI signaling, the disclosure avoids the casethat more bit overheads are introduced into the DCI to support a lowerlatency.

For the case of indicating the HARQ-ACK feedback latency through the RRCsignaling, the disclosure configures multiple HARQ-ACK feedback latencyranges associated to the RNTI, which solves the problem that differentservices have different requirements on latency.

The Layer 1 (L1 layer) 301 is the lowest layer andimplements various PHY (physical layer) signal processing functions. TheL1 layer will be referred to herein as the PHY 301. The Layer 2 (L2layer) 305 is above the PHY 301, and is responsible for the link betweenthe UE and the eNB over the PHY 301. In the user plane, the L2 layer 305includes a Medium Access Control (MAC) sublayer 302, a Radio LinkControl (RLC) sublayer 303, and a Packet Data Convergence Protocol(PDCP) sublayer 304, which are terminated at the eNB on the networkside.

The PDCP sublayer 304 provides multiplexing betweendifferent radio bearers and logical channels. The PDCP sublayer 304 alsoprovides header compression for higher-layer packets so as to reduceradio transmission overheads. The PDCP sublayer 304 provides security byencrypting packets and provides support for UE handover between eNBs.The RLC sublayer 303 provides segmentation and reassembling ofhigher-layer packets, retransmission of lost packets, and reordering oflost packets to as to compensate for out-of-order reception due to HARQ.The MAC sublayer 302 provides multiplexing between logical channels andtransport channels.
